BOSTON (AP) — A jury has ended deliberations for the week without a verdict in the federal trial of a friend of Boston Marathon bombing suspect Dzhokhar Tsarnaev.

Prosecutors say Robel Phillipos lied to the FBI about being in Tsarnaev’s dorm room three days after the bombing, when two other friends removed a backpack containing fireworks and other potential evidence.

Phillipos’ lawyers say he couldn’t clearly remember what happened because he had smoked marijuana heavily that day.

Jurors have deliberated for about 26 hours over four days. They received the case on Tuesday afternoon and deliberated all day Wednesday, Thursday and Friday. Deliberations are expected to resume Monday.

Two bombs that exploded near the marathon finish line on April 15, 2013, killed three people and injured more than 260.
